Ancient oath (part 1)

A few minutes ago:

Daimon and the girls were moving the rocky landscape of the underwater space in which they were, Daimon noticed blood stains from time to time, and clear signs of fight sometimes between people and others between magic beasts.

'Well, those Bottom Shredders need a lot of food, so I guess all the weaker magic beast were already hunted and devoured', he thought.

"Stop", Daimon extended his hand as he asked the girls to stop moving.

"Is there some problem?".

"Did you see something D… Gabriel?".

The girls stopped and asked Daimon why he told them to, once again Leslie nearly called Daimon by her real name, which made her shily giggle while her sisters gazed at her.

Then the girls all saw a huge explosion radiated a large amount of white light, which was visible even from afar.

"That's about ten kilometers away, what is happening?", asked Yvonne, she had to half close her eyes due to the increase in the brightness.
